Megger TRS1 Transformer Ratio Standard

The TRS1 is a unit designed to be used with ratio meters as a high-accuracy reference ratio standard. This unique standard is able to provide ratios in both step-down (traditional ratio test instruments) and step-up (Biddle Hand Crank TTR) test modes. The standard is designed for use as a laboratory calibration standard, or as a portable check standard for field ratio and phase verification of any ratio instrument.

The TRS1 can be used with any single-phase and three-phase ratio meter. Combining three TRS1 units together, one is able to test a Wye-Wye configuration with three phase ratio meters. When testing three-phase ratio meters with the TRS1, one uses the instrument’s single-phase or three-phase excitation for testing. This is meant as a time-saving feature, or to validate TTRU3 phase ratio meter models.
